Monitoring Tips and Guidelines
The ACUMEN Hydra-Alert
TM
provides an indication of the level of
dehydration. The purpose of the dehydration reading is to remind an
individual to drink fluids.
It takes the human body 12 to 24 hours to replace fluids from heat and
exercise. To prevent the harmful effect of excessive dehydration it is
necessary to drink before you become thirsty.
The thirst mechanism is not precise in humans. An individual can lose
fluids equaling up to 3% of their body weight before the thirst mechanism
tells the person they need fluids.
Strength and endurance are reduced by 10-15% after just a 2% loss of
body weight, through dehydration.
Most people need more than eight ounce glasses of water per day. The
water intake each day needs to be half your body weight in ounces. Do
not drink over 32 ounces at any one time. Do not consume more than
four ounce glasses of water in any one hour period. Divide the water
intake over the entire day.
If the exercise period is under 60 to 90 minutes water is always
appropriate. If the exercise period is more than 60 to 90 minutes, a sports
drink offers an energy advantage that can enhance stamina and
endurance.
